Nakamura vs. Ponomariov, Finegold vs. Robson: May 16-25ST. LOUIS, May 12 -- GM Viktor Korchnoi, who was originally scheduled to take on GM Ben Finegold in a 10-game match, has been forced to withdraw due to health concerns. Organizers said the ailment was not serious in nature, but that it impaired Korchnoi's ability to travel internationally. GM Ray Robson will fill Korchnoi's legendary shoes.

The CCSCSL will also host a 10-game match (six classical, four rapid) between St. Louis Grandmaster (GM) Hikaru Nakamura, ranked No. 7 in the world, and GM Ruslan Ponomariov, ranked No. 11 in the world, May 16-25. Nakamura moved up to No. 7 on the live list after GM Veselin Topalov's rating tumbled following his Candidates Match loss to GM Gata Kamsky.

The players will take part in a live, virtual press conference at 10 a.m. CDT on May 16. Journalists and fans from all over the world can log onto livestream.com/uschess to submit questions to the players and watch their answers streamed live online.

Robson, 16, became the youngest grandmaster in U.S. history in 2009 when he was just 14. He had a solid performance at this year's U.S. Championship finishing third in his round-robin field of eight, just a half point shy of qualifying for the finals.
